CIS ELEKTROTECHNIK GMBH Instruction Manual Propeller Shaft Earthing System PES CIS Elektrotechnik GmbH * Wellseedamm 13 24145 Kiel * Germany Tel. +49 431 / 71 97 003 * Fax +49 431 / 71 97 004 * e-Mail: [email protected] www.cis-ship.com 1 CIS ELEKTROTECHNIK GMBH 1. General Description The Propeller Shaft Earthing System „PES” can prevent the micro pitting marks at the propeller and the shaft bearings against spark erosion damages. The high silver tracked slip ring and proven contact brushes ensure a short circuit between the rotating propeller shaft and ship’s hull. The brushes ensure lubrication and long life. Standardized parts and a high prefabrication ensure an easy installation onboard by the technical crew without special tools. The Slip Ring Cleaning Device prevents increase of the potential and keeps the system in good condition over a long period. The remote indicator displays permanently the mV potential between shaft and hull to control the protection of the propeller. As an option there is a remote indicator with alarm relay available. Alternative a 0(4)-20mA signal can be used to monitor the readings to the ships control system. 2. Selection Of Location The location of the System should be clear of spray water and risk of oil and grease contamination. Remove soiling to get a metal clear surface at mounting place on the propeller shaft. The slip ring should not be placed under floor plates if possible to watch the system easily. 3. Installation Of The System Assembly Of The Slip Rings: Each tensioning band is already cut to the right length. Fit the two stainless steel bands loosely on the propeller shaft to provide a temporary support for the two slip ring halves. Place both slip ring halves below the securing bands edge to edge. The tensioning clamps should not be placed side by side and also not on the butt joints. To avoid excessive brush wear it is important, that a smooth track profile is achieved at the joints! If the slip ring joints are not meet satisfyingly, they have to be grinded. Fasten the securing bands and make sure that the tensioning bands are not positioned on the joints and that the slip ring fits tightly to the shaft over the whole length. Seal the sides of the slip rings with insulating material like silicon. 2 CIS ELEKTROTECHNIK GMBH Mounting Of The Brush Holder: The twin brush holder is to mount on the steel spindle PES 105, the single brush holder on the insulated spindle PES 202. Both bolt run parallel to the shaft, mounted to a suitable steel construction. (Drawing PES 001) Drill a slotted hole into the steel construction to adjust the bolt according the distance table drawing PES 001. The distance between twin brush holder and slip ring surface should be 2 - 3mm. Ensure that the brush holder is securing on its bolt. Adjust the brush holder right over the middle of the silver track. (Drawing PES 002) Make sure that the construction is not affected by vibration Mounting Of The Remote Indicator: The remote indicator should be installed at an easily visible, dry and clean place near the PES System. Use the drilling template (drawing PES 003) to mount the indicator to a foundation. Install the cables as mentioned on drawing PES 002 Mounting Of The Slip Ring Cleaning Device: The cleaning device is to mount on the steel bolt of the twin brush holder. Adjust the felt roller right over the middle of the silver track. (Drawing PES 002) 4. Maintenance And Readings Check the cleaning of silver surface, the brushes for mobility and abrasion, the holder and bolts for tightens. 0- mV Incorrect mounting of the system, wear brushes, defect meter, loosen cable Up to 150mV Correct working of equipment Over 150mV Clean the brushes and slip ring. Check the wear of the brushes, the silver surface of the slip rings for wear, the cables and the contacts, the voltage with a separate voltmeter 5. Spare Parts With the Propeller shaft Earthing System „PES” you will get an approved system on high quality standard. Over the last years the different parts were intensively developed and tested. We recommend therefore using only original spare parts. 3 MEASURING TRANSDUCERS FOR DIRECT CURRENT AND DIRECT VOLTAGE IgT-MU / UgT-MU Application The measuring transducers IgT-MU and UgT-MU serve to convert and isolate a direct current or a direct voltage into a load-independent direct-current and direct-voltage signal. The calibrated double-outputs can be switched over between 0-20 mA / 0-10 V and 4-20 mA / 2-10 V. Function The measurable variable gets via an input protective circuit to the amplifier or impedance transformer. The direct voltage obtained is converted into a load-independent direct-current and into an impressed direct voltage. The electrical isolation is effected by means of an optocoupler. Both outputs are no-load resistant and short-circuit proof. Any connection between both outputs will be unacceptable. An auxiliary voltage will be required for all types.
